On the first day you should go there 10 minutes before the start of your lab period and look for the posted lists which will indicate where to go for your introductory lecture. This will last for about an hour. Afterwards, we will proceed to the lab to complete the Check-In/Orientation experiment which is contained in this packet. 5
GETTING STARTED You MUST have the following 3 items before you can be checked into lab: 1. Lab Manual - "PSU Chemtrek" This will be used for both Chem 111 and 113. The current edition is Aug. 2010. The Aug. 2009 version may be used, provided that you write in the updated information (this will be provided upon request). 2. Chem 113 Student Packet, Fall 2010/Spring 2011 - This is what you have in your hand. This contains the course syllabus and other handouts necessary for the course. 3. Chem 111/113 Lab Kit. (With Safety Goggles) If you purchased the kit for a previous semester, then you only need to buy supplies that you have used up. For a typical student this means purchasing (a) a new blank notebook, (b) perhaps a new package of 50 thin stem pipets, and (c) safety goggles. These items are available in the Penn State Bookstore. It would also be a good idea to buy a Scientific Calculator if you do not already own one. It is not important for it to be programmable, but it should be able to handle logs, exponentials, trigonometric functions and scientific notation. WEAR APPROPRIATE CLOTHING - Lab is potentially a messy experience. A T-shirt, blue jeans and shoes (or sneakers) would be reasonable. (No open-toed sandals allowed). We reserve the right to send you home to change if you are not dressed appropriately. 6
THE COURSE VISION Chem 113 is an introductory chemistry laboratory experience that gives students the opportunity to put into practice the essential principles utilized in a professional chemistry laboratory regarding topics relevant to Chem 112. As such, we assume that you are currently taking Chem 112 or have previously taken this course or a course similar in content to it. You will be expected to use information learned in the lecture for the laboratory. Essential Principles: attention to detail proper use of a lab notebook writing of a formal laboratory report use of the literature experimental design interpretation of data/statistics an awareness of safety issues an awareness of environmental issues appreciation for what instruments can and cannot do 7
Dear Chem 113 Students, Welcome to "Part 2" of our General Chemistry Laboratory Program. Most of you have recently completed Chem 111 and are familiar with the "Small Scale" approach used in this course. For those of you who are new to the General Chemistry Laboratories, you should read Chapter 3 of the lab manual which describes the advantages of this approach compared to the traditional experiments. We are one of the first major universities to adopt this approach in both our General Chemistry and our Organic Chemistry Laboratories. But, there is evidence that this is the wave of the future. For example: - The Journal of Chemical Education now has an entire section of each issue devoted to small scale chemistry. - The American Chemical Society (ACS) devoted an entire issue of one of its periodicals to small scale chemistry (ChemUnity News, 1994). The entire issue has been sent to 20,000 chemistry teachers nationwide. - The State of Massachusetts and the Environmental Protection Agency (EPA) have both funded the National Microscale Chemistry Center at Merrimack College. The goal of this Center is to train teachers in small scale techniques. (Chemical and Engineering News, Aug. 9, 1994, pg. 8) - An article appeared in Science entitled, "Innovations in Teaching". One of the people featured in this article was Steve Thompson, the author of Chemtrek (Science, Vol. 266(4), pp. 889-90, 1994). I would also like to point out that this small scale trend in education parallels current developments in research and industry. The same technology which has enabled the computer chip to shrink is enabling the analytical lab to shrink. The day is coming in which you will be able to have an analytical lab in your wrist watch! And, as a result, chemical analyses will be faster, safer, cheaper, and involve less waste... i.e., smaller is better for the 21st Century. Please feel free to talk to me if you have any questions or comments regarding these developments, or any other matters regarding this course. Sincerely, Joseph T. Keiser Director of the General Chemistry Laboratories 8
GRADING Lab Reports Experiments 9, 13, 14, and 18 will require reports that can usually be completed in lab. Some of the labs will contain short homework assignments. These assignments should be completed in labs if time allows, or completed at home if you run out of time in lab. The reports will be due either at the end of lab, or at a time to be announced, often a day or two after the experiment is completed. Instead of a report for Experiment 5, a quiz will be given at the beginning of the following lab period. The quiz and a graphing homework will count as your experiment 5 report grade. (Note: There will not be an Expt. 15 prelab quiz). In addition to an in-lab report for Chromatography, you will be asked to submit a formal type-written report. Late Lab Reports Policy Significant late penalties will result for lab notebooks that are not handed in on the due date. Reports received one week late have a 25 point penalty. Reports that are more than one week late will not be accepted. Quizzes/Test There will be short quizzes given at the beginning of most lab periods according to the schedule on the inside cover. These cover the major points of the experiment of the day. Students who arrive late for lab (i.e., after the quiz has been collected) will receive a zero on that quiz. Contained in this packet are outlines of what you should know for each quiz. There will also be a cumulative lab test given on the last day of lab. An outline of what will be covered on this exam is contained in this packet. Instructor Evaluation The instructor will assign a grade to each student based on their perception of the student's overall performance in the lab. This will include the use of the laboratory notebook, attitude, adherence to safety polices, independence and technique. Lab Monitoring Each student will be assigned one day for which they are responsible for lab monitoring. This will normally entail an end of the period clean up of the shared areas such as the sinks, balances and the chemical supply area. THE FINAL GRADE: Lab Reports: 50% Prelab quizzes: 15% Lab Test: 25% Instructor Evaluation: 10% 100% Teaching Assistants Most of the time you will be working with a Graduate Teaching Assistant (TA). Your TA will supervise your work in the laboratory and grade your reports and quizzes. The final grading decisions, however, will be made by Dr. Keiser. 9
Misc. Policies Attendance Each student is expected to be present in the laboratory at the beginning of each session and to remain in the laboratory for all the scheduled time unless explicit instructions to the contrary are given. A grade of zero will be assigned for any laboratory missed unless permission for a make-up has been given. Make-up Requests If a student has a legitimate excuse for missing a lab (e.g., family emergencies, a note from your Doctor), then he/she should complete a Make-up Request Form (one is on the next page) and drop it off in the mail slot on the cubicle on the 1st floor of Whitmore ASAP. In most cases you will be asked to attend a special make-up experiment which will be held during your normal laboratory period on the week before the lab test. In this case, you will still be held responsible for the material covered on the missed experiment for the lab test. Typically, only 1 makeup lab is allowed. If you find you will miss 2 or more labs, see your section supervisor as soon as possible. Conflict Exams (Usually this only effects the evening lab sections) Many Departments now schedule exams in the evenings. Sometimes these may conflict with a scheduled laboratory meeting. In these cases you are expected to come to lab. If you miss lab to attend an exam, you may receive 0/10 for that days quiz. The Department which is giving the exam is expected to offer you a suitable make-up opportunity. This will normally involve giving you the same exam at a different time. (Note: most Departments have a cut off date for the scheduling of conflict exams. Be sure to check your entire semester s schedule now for lab/exam conflicts.) The Lab Notebook You are expected to keep a detailed and legible laboratory notebook in this course. We will use the notebook as a cross between a professional laboratory notebook, and a lab journal (similar to a diary). Some guidelines on how to do this are given in the section of this packet entitled, "How to Keep a Laboratory Notebook". At the end of each day, you must have the lab instructor sign and date your lab notebook. All original data and observations should be recorded in your lab notebook. Your notebook will typically be turned in at the end of each laboratory period. Lab Neighbors You should feel free to discuss the experiments with your neighbors, but, reports must be written up individually. If information in your notebook comes from someone else, then it must be referenced. The presentation of someone else s work under your name (i.e., without a clear reference) is plagiarism. There are serious penalties for plagiarism, potentially including an F in the course, and an academic dishonesty flag on your transcript. Note: the facilitation of plagiarism, for example by posting your lab reports to the web, is also considered academically dishonest. You should not give a digital copy of your formal report to anyone, including your lab partners, because this tends to encourage plagiarism. A full listing of all Penn State policies on ethics and honorable behavior that apply to this course is given at http://www.psu.edu/ufs/policies/. Open Office Hours Each Chem 113 TA is expected to hold a minimum of one hour per week in the Chemistry Resource Center, room 211 Whitmore. These office hours are open, in the sense that any Chem 113 student may attend the office hour of any Chem 113 TA. (It is still a good idea to go to your own TAs office hour, if possible, since he/she will be more familiar with your work.) Clever Chemist Awards We are interested in identifying and acknowledging students who go "above and beyond" the normal expectations for their lab work. This could be a clever experimental idea, or an especially impressive lab write up, or the discovery of a significant mistake in the lab manual. TA's will make recommendations to the Lab Director. If selected, the student will receive a "Clever Chemist" award. This consists of a unique pair of safety glasses, and a gift certificate to a local store. 10

Information on Eye Protection 7/97 There are three types of eye protection acceptable for use in the Penn State undergraduate chemistry labs. These are described below. You should go to the bookstore and try on the various types, and choose the type that is best for you. 1. Safety Glasses look similar to prescription glasses, but have side shields and a brow bar to prevent extra splash protection. They are generally considered to be more comfortable, and to offer better peripheral vision compared to goggles. The disadvantages are that they do not fit well (if they fit at all) over prescription glasses, and they offer less protection than goggles since they do not cup completely over the eye. The bookstore carries an excellent type of safety glasses called Panaspec Plus by Bouton. This type features a large single lens with side shields and a brow bar. They have the highest level of splash protection of any of the safety glasses examined. 2. Visor Goggles are a type of half goggle, the upper half is similar to a goggle, and the lower half is similar to safety glasses. As such, they have some of the advantages and disadvantages of both safety glasses and goggles. They are reasonably comfortable, afford good splash protection, and offer better peripheral vision and have less tendency to fog than goggles. They fit over many types of prescription glasses. They do have a strap around the head which may be somewhat annoying. The PSU Bookstore carries one brand, Visorgogs (Jones and Company). 3. Goggles are pliable and form a complete cup around the eyes, and are held in place by a strap that wraps around the head. Goggles offer the highest level of splash protection compared to other types of protective eyewear. The disadvantages are that they may fog up, they limit peripheral vision, and the strap may be uncomfortable to some. There are 4 different kinds of goggles available at the Penn State Bookstore. These vary slightly in terms of their shape, design, venting and price. They should fit over prescription glasses. Contact Lens Wearers In 1994, OSHA concluded that contact lenses do not pose additional hazards to the wearer, and has determined that additional regulation addressing the use of contact lenses in unnecessary (1). Other reports support this position (2,3). Therefore, contact lenses will be allowed in the Penn State undergraduate chemistry labs. However, you must wear some type of approved protective eyewear over your contact lenses when you are working in the lab, and you must identify yourself as a contact lens wearer in some manner to be designated by your instructor. This is to alert safety personnel of the presence of your contact lenses in the unlikely event that your eyes would need to be flushed when you are unconscious. 1.
